pairinteraction

Pairinteraction is a computational library and toolset designed for physicists to calculate properties and interactions of Rydberg atoms. The software computes matrix elements of various potentials, including van der Waals and electrostatic interactions, within external electric and magnetic fields. It assists researchers in modeling atomic physics experiments by numerically solving quantum mechanical equations related to multi-atom systems.

The application relies on Python and C++ components to handle heavy numerical routines, making it suitable for integration into automated calculation workflows on Linux operating systems. Users specify atomic states, quantum numbers, and field parameters to generate interaction potentials and state diagrams.
